I guys are following the discussion :)
Whit my bad english it's already difficult to made an example........

Damn... when i made the video whit GB and CATRAP for the other my thread I could show you the example of this too :)

I also had to post the gamelist.xml but it just passed my mind ... really sorry ...

You have two options:

Stick with official plug and play devices like (s)nes classic mini Start a new hobby creating your own personalized Retropie system by starting from scratch. It's not that hard. All the information is readily available on this website. You may want to invest in a quality micro sd card first.

@maplestory Correct. It doesn't matter. Those lines relate to the extra folders - nvram, etc.

Thanks for reporting! Hope you're having fun.

Rogue and nethack would probably work, but likely need a keyboard. I'm not sure how many buttons are needed to make that really playable with just a joypad.

I recently came across pico-8, seems inexpensive and ports to run on RPi, development environment, etc.

Yeah, basically that. I feel daft now; I actually searched google for the terms "retropie randomizer" and all I got was stuff about splashscreens.
Thanks though, I'll give the kid mode rom roulette a try later and see if it's functional. Does anyone know if we CAN bring this feature to the normal ES mode with a script or something?

So, the random select seems to be working, and displaying the subfolders from what I can see. Great!

However, now when I select Shutdown System, it goes to a black screen with a blinking _ underscore instead of shutting off.

Edit: the same thing happens when I F4 out to he command line. The command line never appears, only the blinking underscore and black screen.

@BuZz Thanks mate :)

please have a thorough read of the complete wiki page, particularly https://github.com/retropie/retropie-setup/wiki/Child-friendly-EmulationStation#installation.
Again, make backups, expect bugs.

@madmodder123 there is a randomiser built in to the splash screen module already...
